IRR (incidence rate ratio), which is defined as e ^B, where B is the regression coefficients.

Model 1: adjusting a baseline covariates, including age, gender, educational attainment, IMD tertile, weight status, and number of self-reported chronic illnesses, and also GP Management System, and time lapse to follow-up;

Model 2: additionally adjusting for lower limb function.
